Cavity and flat plate receivers: RYTRX is the ratio
RY(I)/RX(I), assumed the same for all apertures or flat
plates. RXZTRX is the ratio RX(Z)/RX(l), etc. (See REC

In a land constrained design (NLAND > 0, below) NUMPOS
discrete, equally spaced values of the tower location#
relative to the origin used to describe the land constraints
are tested. The tower positions lie along a line
specified by the coordinates of the first tower position
(XTPST m east, YTPST m north) and the last tower
position (XTPEND m east, YTPEND m north).
